A Data Trusted Transmission Mechanism for IOT Based on Merkle Tree

In order to solve the communication security problem between clusters and clusters. This paper proposes a data-trusted transmission mechanism based on Merkle authentication, which guarantees the correctness, integrity, confidentiality and reliability of intra-cluster transmission and inter-cluster transmission messages. It can resist security problems such as forgery attacks and anti-replay attacks to a certain degree. The method adopts a hierarchical multipath routing scheme based on Merkle tree authentication. The hierarchical multipath routing scheme routes data by using multiple paths, can bypass malicious nodes to a certain extent, improve the reliability of the network, and even if the malicious node intercepts the data, it cannot know the complete information of the data.
